Possible Causes

Loose mounting screws on heating plate, Warped inner pot bottom, Foreign object between pot and plate, Damaged spring support under plate

Safety first: Unplug and cool the cooker before inspection.

Check for foreign objects: Remove the inner pot and inspect the heating plate for debris, grains, or utensils.
Inspect pot bottom: Replace the inner pot if the bottom is significantly warped or dented.
Tighten plate screws (advanced): Access the underside and gently tighten the screws holding the heating plate to the chassis.
Accept minor clicks: Some light clicking from thermal expansion is normal, but loud or grinding noises indicate a mechanical issue that should be corrected.
